Progesterone suppositories

How far along were you all when you started taking them?? I’m about 5 or 6 weeks along and I took a blood test last Thursday and didnt find out until today that my progesterone was low. They said the doctor wasn’t there at the time to discuss the details 🙄🙄🙄 so I have to wait until Wednesday for my appointment. But in the mean time I am prescribed 100mg suppositories vaginally every night. I’m just wondering if I’m okay being as though this whole time my level has been low and I’m just now taking the suppositories?? 😩😩😩😩😩
